Abstract
The regenerative properties of the «UltraCell-Dog» drug, obtained from the dog mesenchymal stem cell secretomе, were studied during early stages of the reparative process after modeling injury in rats. It was shown that the «UltraCell-Dog» stimulates the angiogenesis in the defect zone, promotes the formation of bone and cartilage tissue without structural disturbances. The data of biochemical analysis indicate a higher intensity of cartilage and bone tissue repair in the experimental group at the early stages of therapy. The regenerative properties of the «UltraCell-Dog» low-molecular (up to 50 kDa) peptide drug obtained from the secretion of dog mesenchymal stem cells were studied using a model of traumatic knee injury. It was shown histologically that «UltraCell-Dog» promotes the formation of bone and cartilage tissue without structural disturbances, and stimulates angiogenesis in the defect zone in the early stages of the reparative process. Biochemical assay data indicate a higher rate of recovery of cartilage and bone tissues in the experimental group comparing to the control.
